Evaluation of ecological environment quality in some regions of Tianjin based on remote sensing ecological index

In the context of carbon peak and carbon neutrality, people are increasingly concerned about the quality of ecological environment. And remote sensing technology can realize dynamic monitoring of ecological environment quality. This paper evaluated the quality of ecological environment in Tianjin area by remote sensing technology to provide basis for the management and protection of ecological environment in this area. We selected the landsat-8 OLI images from 2014 to 2020 and obtain the remote sensing ecological index RSEI to analyze the spatiotemporal evolution of ecological environment quality in study area. The results show that the RSEI model can simulate the ecological environment quality in study area. And the influence of different indicators on the ecological environment is complex. From 2014-2017, there was a significant improvement in the ecological and environmental quality of study area. And the ecological and environmental quality of study area slightly deteriorated from 2017 to 2020.
